Official description

Package [email protected] contains 2 files with no a static rule matches and no traced behavior indicating exfiltration, install-time code execution, credential access, silent relay, backdoor, or self-propagation. The random-looking package name is unusual and may indicate a placeholder, test upload, or throwaway publication, but the shipped code does not demonstrate any mechanism that harms an installer.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

What should I do about MAL-2026-13839?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
